Stainless Steel Carbon Steel Nylon Lock Nut Nylon Insert Nut

This series of nylon locking nuts (also known as self-locking nuts or nylon caps) is an efficient anti-loosening fastener specially designed to solve the problem of loose threaded connections. The core of the product adopts an integrated structure of "hexagonal nut body + high-temperature-resistant nylon ring". During the tightening process, the nylon ring is deformed by the threaded part of the bolt, and through continuous and uniform gripping force, it locks the threads, effectively resisting the pre-tightening force attenuation caused by vibration, impact, and temperature changes, and completely eliminating the problem of connection loosening.

We offer three mainstream versions, covering all scenarios:

304 stainless steel original color model

Galvanized zinc carbon steel model

Oxidized black carbon steel model

No additional elastic pads are required. A single nut can achieve the anti-loosening effect, which is an upgraded solution replacing the traditional "nut + elastic pad" combination, and is suitable for various industrial and civilian threaded connection scenarios.

High-efficiency anti-loosening, long-lasting effectiveness

Unlike traditional spring washers that rely on elastic force for anti-loosening, the nylon ring generates a persistent locking force through the interlocking with the threads. In high-frequency vibration conditions, its anti-loosening effect far exceeds that of ordinary nuts, is less prone to loosening or slipping, and significantly reduces equipment maintenance costs.

Multi-version full-scenario compatibility, choose as needed

304 stainless steel model: Excellent corrosion and rust prevention performance, does not rust even in humid, outdoor, or coastal environments for long-term use;

Dipped zinc-carbon steel model: A cost-effective choice, with basic rust prevention capabilities, suitable for most conventional industrial scenarios;

Blackened carbon steel model: High surface hardness, wear-resistant and scratch-resistant, suitable for heavy loads, oil stains, and high-frequency vibration conditions.

Installation is convenient, with full adaptability

No additional accessories are required, a single nut can complete the anti-loosening installation, and the steps are halved compared to traditional solutions; strictly following national standards for production, with high thread precision, perfectly compatible with standard metric bolts, and smooth tightening without slippage or jamming.

Temperature resistance and aging resistance, long service life

Using high-quality temperature-resistant nylon rings, they do not age or deform easily during long-term use, have stable locking force, can maintain anti-loosening performance in a wide temperature range of -40℃ to 120℃, and are suitable for complex working conditions.

Stainless steel model: Outdoor photovoltaic supports, water conservancy equipment, ship accessories, kitchen and bathroom appliances, coastal facilities, etc. in humid / corrosive environments;

Galvanized color model: General mechanical equipment, electrical equipment, automotive parts, building curtain walls, furniture hardware, etc. in common industrial scenarios;

Blackening model: Construction machinery, mining equipment, machine tools, heavy-duty equipment, vehicle chassis, etc. in high-frequency vibration / oil-soiled conditions;

All series general: Automation equipment, rail transit, communication cabinets, outdoor guardrails, storage shelves, etc. for all threaded connection scenarios that require anti-loosening protection.

Packaging protection: We use industrial-grade packaging that is moisture-proof and rust-proof. The products are individually packaged in bags or boxes according to specifications, with built-in pressure-reducing and cushioning materials to prevent the nylon rings from deforming and the nuts from being knocked and rusted during transportation. The quantity is clearly marked for easy inventory checking.

Delivery time: Standard specifications are ready for shipment within 48 hours. Customized specifications are produced according to the order cycle. The entire process can track the logistics information.

Logistics coverage: We cooperate with national logistics channels. We support bulk vehicle transportation and scattered express delivery. For remote areas, we can choose dedicated logistics services as needed to ensure the safe and punctual delivery of the goods.
